IMPROVEMENT-IN, MECHANICAL MOVEMENTS.

Specification forniingpart of Letters Patent not 115,406, dated May 30,1871; antedated May 17, 1871.

I, JAOOn WOOIiF, deem Oak, in the county of St. Joseph and State of Michigan, have invented a new and useful Mechanical Move- -ment, of which the following is a specification:

A Nature and Objects of the Invention.

My.' device is constructedjwith onegr rnore weights attached tolilever armifid carried around in a'horizontal or'nearly horizontal plane beneath a fcanrsurface, by which the weights are raised, with a slight. expenditure of power, by agradual movement extending gravity.

Description of the Accompanying Drawing.

Figure 1 is a planor top view of the appa ratus; Fig. 2 is a side elevationof the same.

General Description. -Ajrepresentsfazvertical' shaft mounted on a bed,'B, and supporting astationary cam on rim, 0, the under surface of which forms an inclined plane, either descending gradually and continuously throughout the circuit, as

showni-nlFig. 2, or divided into two or more steps or sections. ASIGGVG, D, fitted to turn freely on the shaft A, carriesa bevel-pinion,

E, or other means of driving it, and a wheel, F, to which are pivoted one or more levers, G, on the forward ends of which are weights H. i The rear ends of the said levers are provided with friction-rollers I, which are pressed upward against the inclined plane 0 by the gravity of the weightsH.

' l Operation. The sleeve D and wheel F being rotated by any convenient power in the direction indi cated by the arrow, the weights H will be gradually elevated by the depression of the rear" ends of the lever G as they are carried around under the stationary cam or cams O, and as each one arrives at the end of the incline, or of each incline where more than one is used, the weight is allowed to descend, and the entire power of its gravity is applied to any mechanism which it is desired to operate with a heavy descending force.
